Very miss-leading advert as does not work on all Imac's. customer service is awful from seller and I wont be using this company again. AVOID!!!!!
1. Went to the site.
2. Purchased what I needed.
3. Email arrived within literally seconds after purchase.
4. Applied item with no problems.
No issues what so ever with the key!
Worked so well I then bought a windows server one that worked just as well.
